Audiovisual angle and voice incongruence do not affect audiovisual verbal short-term memory in virtual reality.

Virtual reality (VR) environments are frequently used in auditory and cognitive research to imitate real-life scenarios. The visual component in VR has the potential to affect how auditory information is processed, especially if incongruences between the visual and auditory information occur. This study investigated how audiovisual incongruence in VR implemented with a head-mounted display (HMD) affects verbal short-term memory compared to presentation of the same material over traditional computer monitors.

Noise disturbance and lack of privacy: Modeling acoustic dissatisfaction in open-plan offices.

Open-plan offices are well-known to be adversely affected by acoustic issues. This study aims to model acoustic dissatisfaction using measurements of room acoustics and sound environment during occupancy, and occupant surveys (n = 349) in 28 offices representing a diverse range of workplace parameters. As latent factors, the contribution of lack of privacy (LackPriv) was 25% higher than noise disturbance in predicting acoustic dissatisfaction (AcDsat).

Differential Effects of Task-Irrelevant Monaural and Binaural Classroom Scenarios on Children's and Adults' Speech Perception, Listening Comprehension, and Visual-Verbal Short-Term Memory.

Most studies investigating the effects of environmental noise on children's cognitive performance examine the impact of monaural noise (i.e., same signal to both ears), oversimplifying multiple aspects of binaural hearing (i.

Effect of voice support level and spectrum on conversational speech.

One's own voice (autophony) is transmitted to the ears as direct airborne sound, bone conduction, and indirect airborne sound from reflections characterized by overall gain and spectro-temporal features. This study investigates how the spectral profile and gain of simulated indirect airborne sound, quantified as voice support (ST), affect the speaking voice of talkers. Pairs of participants performed a conversation elicitation task in anechoic conditions.

Chamber musicians' acoustic impressions of auditorium stages: Relation to spatial distribution of early reflections and other parameters.

Characterizing stage acoustics using objective parameters has seen some recent resurgence-several studies have noted the importance of the directionality of early stage reflections to musicians, which is not adequately represented using existing omnidirectional stage-support parameters. This study examines the subjective impressions of 19 chamber musicians against omnidirectional [reverberation time, early and late support (ST, ST), etc.], and proposed spatially-defined parameters (TH and TS), along with simple ratios of stage dimensions derived from measurements on eight purpose-built stages.

Autophonic Loudness of Singers in Simulated Room Acoustic Environments.

Objectives: This paper aims to study the effect of room acoustics and phonemes on the perception of loudness of one's own voice (autophonic loudness) for a group of trained singers.

Methods: For a set of five phonemes, 20 singers vocalized over several autophonic loudness ratios, while maintaining pitch constancy over extreme voice levels, within five simulated rooms.

Results: There were statistically significant differences in the slope of the autophonic loudness function (logarithm of autophonic loudness as a function of voice sound pressure level) for the five phonemes, with slopes ranging from 1.

Assessing Linearity in the Loudness Envelope of the Messa di Voce Singing Exercise Through Acoustic Signal Analysis.

Messa di voce (MDV) is a singing exercise that involves sustaining a single pitch with a linear change in loudness from silence to maximum intensity (the crescendo part) and back to silence again (the decrescendo part), with time symmetry between the two parts. Previous studies have used the sound pressure level (SPL, in decibels) of a singer's voice to measure loudness, so as to assess the linearity of each part-an approach that has limitations due to loudness and SPL not being linearly related. This article studies the loudness envelope shapes of MDVs, comparing the SPL approach with approaches that are more closely related to human loudness perception.

Towards a method for loudness-based analysis of the sound of one's own voice.

This paper outlines the steps in objectively estimating the time-varying loudness of one's own voice in a room (i.e. autophonic loudness).
